Runtime error when calling on SpellUI to enable spelling

Question

I run into a problem with SpellUI in the Squiggly package that is just released. I am trying to use Squiggly for an Air 2.0 application with Flex 4.0.0 sdk, and my IDE is Flash Builder 4.0.0.
When I have an event handler method that calls on either SpellUI.enableSpelling() or setSpellingMenuEntries(), no matter the code is in a mxml component or an AS class, an error #1014 will occur during the time when the UI component or the class is loaded from a module that is built as a swf. If I choose to ignore the error and call on the event handler, nothing happens. The following is the stack trace message:
VerifyError: Error #1014: Class mx.flash::UIMovieClip could not be found.
    at flash.display::MovieClip/nextFrame()
    at mx.core::FlexModuleFactory/deferredNextFrame()[E:\dev\4.0.0\frameworks\projects\framework \src\mx\core\FlexModuleFactory.as:631]
    at mx.core::FlexModuleFactory/update()[E:\dev\4.0.0\frameworks\projects\framework\src\mx\cor e\FlexModuleFactory.as:401]
    at mx.core::FlexModuleFactory/moduleCompleteHandler()[E:\dev\4.0.0\frameworks\projects\frame work\src\mx\core\FlexModuleFactory.as:718]
I tried to invoke SpellUI in the Air example project "UserDictionaryExample" attached in the downloaded package, I got a similar error as shown below, but the applicaiton still works.
VerifyError: Error #1014: Class IIMEClient could not be found.

As I can tell, the major difference between my app and the example is that my app uses spark components, including the top WindowedApplication. Another difference is that my component is loaded from a swf, whereas the exmple does not do that. Is SpellUI tested with Air 2.0, spark, and modules? Does anyone have any idea what the problem could be? Any help would be greatly appreciated!
Thanks!

Thanks for your response and tests.
I figured out the problems and fixed it with a workaround to make it work for spark TextArea as you also tested.
But the workaround is not the way I want. I have an air application project with several module projects, and at runtime the modules are loaded dynamically as swfs. One of the mudules is built as a runtime shared library. That "class not found" error will go away ONLY IF the SpellUI class is forced to be built into the runtime shared library that loads other modules dynamically, including the one containing the text editor control that uses squiggly for spelling check. Ideally, I should not do that. But it seems the only way I can get rid of the error and make SpellUI work. Interestingly, I don't have this kind of problem with SpellChecker class, which is from a different swc. This seems to me is a build issue, but I am not sure. Do you have any idea why I have to do that and why SpellUI behaves differently than SpellChecker?
In addition to the above issue, I found SpellUI doesn't work for spark.components.RichEditableText. When I call SpellUI.enableSpelling() on it, nothing happens and no exception is thrown. If RichEditableText is not currently supported, do you have an plan to support RichEditableText in the future?
Thanks again.
